SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 349,922, dated September 28, 1886.

Application filed July 20, 1886. Serial No.208,552.

To all whom it may concern.-

Be it known that 1, JAMES H. OoRsBIE, a citizen of the United States, residing at Hartsells, in the county of Morgan and State of Alabama, have invented a new and useful Improvement in Sash Holders and Balances, of which the following is a specification.

My invention relates to combined sash holders and balances; and the invention consists in certain peculiar and novel features of construction and arrangement, as hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in

which- Figure 1 is a front elevation of a window and frame with my improvements applied thereto. Fig. 2 is a side elevation of the fastener. Fig. 3 is a reversed view of the same.

In the said drawings, A designates the window-frame; B, the top sash, and G the bottom sash, of the same.

D designates my improved fastener, which is composed of a plate, (1, preferably of oblong rectangular form, as shown, and provided on its rear side with a V-shaped recess, d, the sides of which are serrated and converge upwardly, as shown. From the back of this re- 0 cess opens a slot, (1*, which extends transversely to the length of the plate d. vd designates a V- shaped slide, the sides of which are serrated and converge upwardly, as shown. On its outer side this slide carries a pin, d,

3 5 which projects through the slot (2 At the middle of the upper end or head of the frame A are secured two pulleys, a, and at each upper corner of said frame is placed a pulley, a.

E E designate two cords, which are secured at one end to the upper sash, B, at about the middle of its sides. These cords extend up (No model.)

over the pulleys a, from thence over the pulleys a, and down between opposite sides of the slide d and recess 01, as shown. The teeth or serrations on the sides of the recess d and slide d point downward, so that as the weight of the lower sash comes upon the cords E the slide (1 of fastener D, which is secured to the top or meeting rail, 0, of lower sash,O, will be drawn upward and bind the cords, and so that the lower sash will be held in any position. By pulling down upon the pin d" the lower sash may be adjusted to anydesired position.

The device is extremely simple and durable, and may be made of wood or metal,as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a sash holder and balance, the combination of a suitable frame or casing, the central guide-pulleys, a, journaled thereon, the guidepulleys a, arranged at the outer sides of the frame, the upper and lower sashes, a slotted plate, (I, affixed to the lower sash in line with 05 the central guide-pulleys, a, and having a recess, d, formed with the converging and serrated sides, the slide fitted in the recess of the plate, and having the converging and serrated sides corresponding with the side of the re- 0 cess, and a pin which works in the slot of the plate, and the cords secured to the sides of the upper sash and passing. over the guide-pulleys a a, and through the recess in the plate, all arranged and adapted for service substantially as and for the purpose set forth.

I11 testimony thatl claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JAMES H. CORSBIE.
